Between January and March 2023, Gakken released three new products: "Kaimono Street," a money learning application, "Sansu Land," an educational math application for young children, and "Dragon Drill" App Version. Each of these apps uses a curriculum based on Gakken's expertise in producing educational materials, and we propose a new learning style with ingenuity for fun learning unique to apps, such as music, animation, and repetitive learning.
